Which of the following are antiviral drug classes used in the treatment of HIV/AIDS?

Correct Answer: D

Rationale: The correct answer is 'All of the above.' Nucleoside reverse transcriptase inhibitors inhibit the enzyme reverse transcriptase, protease inhibitors block the activity of the HIV-1 protease enzyme, and HIV fusion inhibitors prevent HIV from entering human cells. Therefore, all the choices provided are valid antiviral drug classes for managing HIV/AIDS. Nucleoside reverse transcriptase inhibitors, protease inhibitors, and HIV fusion inhibitors play crucial roles in combating the virus at different stages. Nucleoside reverse transcriptase inhibitors target an early stage, protease inhibitors act on a later stage, and HIV fusion inhibitors prevent viral entry. Thus, 'All of the above' is the correct and comprehensive answer encompassing different mechanisms of action in managing HIV/AIDS.

Correct Answer: A

Rationale: Padding on a restraint helps distribute pressure to prevent bony prominences from bearing excessive pressure when a client pulls against the restraints. This is crucial to avoid tissue damage caused by ischemia. The correct answer focuses on the physiological benefit of padding in reducing pressure on vulnerable areas to prevent harm. Choice B is incorrect as the primary purpose of padding is not emotional comfort but preventing physical harm. Choice C is incorrect as while padding can indirectly help prevent infection and wounds by reducing pressure, its primary function is pressure distribution. Choice D is incorrect as the main purpose of padding is not to keep the restraints in place but to protect the client's skin and tissues from pressure-related injuries.

Correct Answer: A

Rationale: The correct statement is, '"I should wear earplugs during the test,"?' as MRI scanners produce loud noises requiring ear protection. Metal objects, including jewelry, are not allowed inside the MRI room due to safety concerns related to the magnetic field. Choices B, C, and D are incorrect. Choice B is wrong because metal objects, including jewelry, are not permitted in the MRI room. Choices C and D are incorrect as having a pacemaker or an artificial hip raises concerns due to the magnetic field in MRI, requiring special precautions or considerations. It is crucial for individuals with such implants to inform their healthcare provider to assess the risks and determine the appropriate course of action.

Correct Answer: C

Rationale: Following a recent tattoo, someone should be screened for hepatitis. Tattooing puts a client at risk for blood-borne hepatitis B or C if strict sterile procedures are not followed. Tuberculosis is an airborne pathogen, while herpes and syphilis are spread through direct contact like sexual activity. Therefore, hepatitis is the most relevant infection to screen for after getting a tattoo.

Correct Answer: C

Rationale: The correct answer is 4.0 mEq/L. Normal serum potassium levels typically range from 3.5-5.5 mEq/L. Choice A (1.5 mEq/L) is below the normal range, Choice B (3.0 mEq/L) is also below the normal range, and Choice D (6.0 mEq/L) is above the normal range. Therefore, the only option within the normal range is Choice C (4.0 mEq/L).
